Abstract
Description
Technical Field
[0001] This application belongs to the field of laser cutting tools, and particularly relates to a tool bar adjustment seat for laser cutting. Background Art
[0002] In the prior art, a groove is formed in the table frame, and a carbon dioxide tool bar is placed in the card slot to fix the tool bar and prevent the tool bar from shaking. However, in this method, when the table frame is welded and deformed or the tool bar itself is deformed, after the tool bar is placed, the tool bar and the table cannot be completely fitted, and the tool bar is likely to displace and shake during the processing; and there are dimensional errors during the processing of the table frame. Therefore, after the tool bar is placed, a gap is formed between some tool bars and the table frame, resulting in easy shaking of the tool bar during the processing.
[0003] In the prior art laser cutting machine, when cutting parts at high speed, the shaking of the tool bar easily causes the processing path to deviate, and at the same time, the tool bar in contact with the part to be processed will drive the part to shake, resulting in unqualified part processing. Utility Model Content
[0004] This application provides a tool bar adjustment seat for laser cutting, which solves the problem that the tool bar and the table frame cannot be completely fitted, resulting in shaking of the tool bar and driving the workpiece to shake during the processing, affecting the processing quality.
[0005] The technical solution adopted in this application is as follows:
[0006] A tool bar adjustment seat for laser cutting, including a table frame fixed to the bed of the cutting machine, the table frame is provided with a card slot for positioning the tool bar, the adjustment seat is fixed to the table frame through a limiting structure, the limiting structure includes an adjusting component, the adjusting component includes a first screw connecting the adjustment seat and the table frame and a compression spring sleeved outside the first screw, the first screw rotates clockwise and counterclockwise to drive the adjustment seat to lift relative to the table frame, so that the top surface of the adjustment seat abuts against the bottom surface of the tool bar.
[0007] In addition to setting a card slot in the table frame to limit the tool bar, this solution additionally sets an adjustment seat and a limiting structure to cooperate with the table frame to stably limit the tool bar. The height of the adjustment seat is adjusted through the adjusting component, so that the adjustment seat replaces the table frame to abut against the tool bar, and the adjusting component realizes the height adjustment of the adjustment seat through the screwing in or out of the first screw, in cooperation with the compression spring, so that the adjustment seat abuts against the tool bar. At the same time, the adjustment seat is fixed to the table frame through the limiting structure. The axial displacement and radial displacement of the tool bar are both limited through the card slot and the adjustment seat, thereby avoiding the shaking of the tool bar during the processing.
[0008] The compression spring is located above the adjustment seat, and at least a part of the bottom coil of the compression spring abuts against the top wall of the adjustment seat.
[0009] The compression spring is arranged above the adjustment seat, which is convenient for the installation of the compression spring. The compression spring is sleeved outside the first screw, and its bottom abuts against the top wall of the adjustment seat. The first screw passes through the adjustment seat and the table frame at the same time. When the bottom of the compression spring abuts against the top wall of the adjustment seat, during the process of tightening or loosening the first screw, the compression spring always abuts against the top wall of the adjustment seat. It can be understood that the upper end of the compression spring abuts against the first screw. Then, during the rotation of the first screw, the compression spring limits the relative position between the first screw and the adjustment seat, preventing the first screw from falling due to loosening. When the first screw is screwed in, the compression spring transfers the pressure to the adjustment seat, and the adjustment seat moves downward, shortening the distance from the table frame bracket. Similarly, when the first screw is screwed out, the compression spring elongates, the force on the adjustment seat decreases, the adjustment seat moves upward, and the distance from the table frame increases. At the same time, due to the fixation of the limiting structure, the adjustment seat and the table frame are always connected. In this way, the height of the adjustment seat is adjusted to make the adjustment seat have a suitable height to abut against the cutter bar.
[0010] The limiting structure includes a positioning component, and the positioning component includes a second screw, and the second screw cooperates with a nut to fixedly connect the adjustment seat and the table frame.
[0011] The positioning component fixes the adjustment seat and the table frame. After the adjustment component adjusts the height of the adjustment seat, the adjustment seat is fixed on the table frame through the positioning component, so as to ensure the overall stability of the adjustment seat at the limited height during the processing.
[0012] The adjustment seat and the table frame are provided with assembly holes for the first screw and the second screw to pass through, and the inner diameter of the assembly hole is smaller than the outer diameter of the compression spring.
[0013] Setting the inner diameter of the assembly hole to be smaller than the outer diameter of the compression spring prevents the compression spring from falling into the assembly opening, which is beneficial to ensuring the stable limiting function of the compression spring.
[0014] The limiting structure includes a plurality of connecting units distributed along the adjustment seat, and each connecting unit includes the adjustment component and the positioning component.
[0015] Setting the connecting unit to include the adjustment component and the positioning component. After adjusting the height of the adjustment seat to abut against the cutter bar, it is fixed through the positioning component to prevent the adjustment seat from being unstable due to the chaotic distribution of the adjustment component and the positioning component.
[0016] The adjustment seat is provided with a plurality of limiting plates arranged along the length direction of the cutter bar, and each limiting plate is provided with a plurality of card slots.
[0017] The top of the limiting plate is concave to form the clamping groove, and each limiting plate corresponding to a single cutter bar is provided with the clamping groove connected thereto.
[0018] Each limiting plate is arranged corresponding to a single cutter bar and is provided with a clamping groove engaged therewith, so that the clamping and limiting are performed at multiple positions of a single cutter bar, thereby ensuring the limiting stability of the whole cutter bar. And each limiting plate is provided with a plurality of clamping grooves along its own length, and can be simultaneously engaged with a plurality of cutter bars.
[0019] A plurality of limiting plates are provided, and the clamping grooves include a first clamping groove and a second clamping groove which are axially offset along the length direction of the cutter bar. Each limiting plate is provided with the first clamping groove or the second clamping groove, and at least two limiting plates at both ends are provided with the first clamping groove.
[0020] The first clamping grooves are arranged in a counterpoint manner on the limiting plates at both ends to determine the basic position of the cutter bar. The second clamping grooves which are axially offset from the first clamping grooves at both ends are arranged on the middle limiting plates. Then when the cutter bar has a tendency to move, due to the offset between the first clamping groove and the second clamping groove, the left and right side walls of the cutter bar are respectively abutted against the first clamping groove and the second clamping groove, and cannot continue to move left or right, thus avoiding the radial shaking of the cutter bar. At the same time, the adjusting seat cooperates with the clamping groove to perform vertical movement limiting on the cutter bar. By this way, the working stability of the cutter bar during laser cutting is further improved.
[0021] A clearance area is provided between the adjusting seat and the table frame, the compression spring is located in the clearance area, and the upper and lower ends of the compression spring respectively abut against the adjusting seat and the table frame.
[0022] The adjusting seat includes a top plate abutting against the cutter bar and side plates located on both sides of the top plate and extending vertically downward, and the clearance area is formed between the top plate and the table frame.
[0023] The compression spring is arranged in the clearance area, its upper end abuts against the adjusting seat, and its lower end abuts against the table frame. When the first screw is screwed in or out, the compression spring contracts or elongates, and still generates a force on the adjusting seat and the table frame during this process, and still can realize the height adjustment and limiting of the adjusting seat.
[0024] Due to the adoption of the above technical solution, the beneficial effects obtained by the present application are as follows:
[0025] (1) In addition to setting a clamping groove on the tabletop frame to limit the tool bar, an adjustment seat is additionally provided to cooperate with the limiting structure to stably limit the tool bar with the tabletop frame. The height of the adjustment seat is adjusted by an adjustment component, so that the adjustment seat replaces the tabletop frame to abut against the tool bar. And the adjustment component realizes the height adjustment of the adjustment seat by screwing in or out the first screw, cooperating with the compression spring, so that the adjustment seat abuts against the tool bar. At the same time, the adjustment seat is fixed on the tabletop frame through the limiting structure. Through the clamping groove and the adjustment seat, the axial displacement and radial displacement of the tool bar are both limited, thereby avoiding the shaking of the tool bar during the processing.
[0026] (2) The compression spring is arranged above the adjustment seat, which is convenient for the installation and setting of the compression spring. The compression spring is sleeved outside the first screw, and its bottom abuts against the top wall of the adjustment seat. The first screw passes through the adjustment seat and the tabletop frame at the same time. When the bottom of the compression spring abuts against the top wall of the adjustment seat, during the process of tightening or loosening the first screw, the compression spring always abuts against the top wall of the adjustment seat. It can be understood that the upper end of the compression spring abuts against the first screw. Then during the rotation of the first screw, the compression spring limits the relative position between the first screw and the adjustment seat, avoiding the dropping of the first screw due to loosening. When the first screw is screwed in, the compression spring transfers the pressure to the adjustment seat, and the adjustment seat moves down, shortening the distance from the tabletop frame support. Similarly, when the first screw is screwed out, the compression spring elongates, the force on the adjustment seat decreases, the adjustment seat moves up, and the distance from the tabletop frame increases. And at the same time, due to the fixation of the limiting structure, the adjustment seat and the tabletop frame always remain connected. In this way, the height adjustment of the adjustment seat is realized, so that the adjustment seat has a suitable height to abut against the tool bar.
[0027] (3) First clamping grooves are arranged in a counterpoint manner on the limiting plates at both ends to determine the basic position of the tool bar. The middle limiting plate is provided with second clamping grooves axially misaligned with the first clamping grooves at both ends. Then when the tool bar has a tendency to move, due to the misalignment of the first clamping grooves and the second clamping grooves, the left and right side walls of the tool bar respectively abut against the first clamping grooves and the second clamping grooves, and cannot continue to move left or right. In this way, the radial shaking of the tool bar is avoided. At the same time, the adjustment seat cooperates with the clamping groove to limit the vertical movement of the tool bar. In this way, the working stability of the tool bar during laser cutting is further improved. Description of the Drawings

[0041] The solution of this application provides an adjusting seat for a knife bar used in laser cutting, as Figures 1 to 5 shown, which includes a table frame 1 fixed to the bed of the cutting machine. The table frame 1 is provided with a slot 5 for positioning the knife bar 7. The adjusting seat 2 is fixed to the table frame 1 through a limiting structure. The limiting structure includes an adjusting component 3. The adjusting component 3 includes a first screw 31 connecting the adjusting seat 2 and the table frame 1 and a compression spring 32 sleeved outside the first screw 31. The first screw 31 rotates in the clockwise and counterclockwise directions to drive the adjusting seat 2 to lift relative to the table frame 1, so that the top surface of the adjusting seat 2 abuts against the bottom surface of the knife bar 7.
[0042] In addition to setting the slot 5 in the table frame 1 to limit the knife bar 7, this solution additionally sets the adjusting seat 2 to cooperate with the limiting structure and the table frame 1 to stably limit the knife bar 7. The height of the adjusting seat 2 is adjusted through the adjusting component 3, so that the adjusting seat 2 replaces the table frame 1 to abut against the knife bar 7. And the adjusting component 3 realizes the height adjustment of the adjusting seat 2 through the screwing in or out of the first screw 31, in cooperation with the compression spring 32, so that the adjusting seat 2 abuts against the knife bar 7. At the same time, the adjusting seat 2 is fixed to the table frame 1 through the limiting structure. Through the slot 5 and the adjusting seat 2, the axial displacement and radial displacement of the knife bar 7 are both limited, thereby avoiding the shaking of the knife bar 7 during the processing.
[0043] In a preferred embodiment, as Figure 2 、 Figure 3 shown, the compression spring 32 is located above the adjusting seat 2, and at least part of the bottom coil of the compression spring 32 abuts against the top wall of the adjusting seat 2.
[0044] The compression spring 32 is arranged above the adjustment seat 2, which facilitates the installation of the compression spring 32. The compression spring 32 is sleeved outside the first screw 31, and its bottom abuts against the top wall of the adjustment seat 2. The first screw 31 passes through the adjustment seat 2 and the table frame 1 at the same time. When the bottom of the compression spring 32 abuts against the top wall of the adjustment seat 2, during the process of tightening or loosening the first screw 31, the compression spring 32 always abuts against the top wall of the adjustment seat 2. It can be understood that when the upper end of the compression spring 32 abuts against the first screw 31, during the rotation of the first screw 31, the compression spring 32 limits the relative position between the first screw 31 and the adjustment seat 2, preventing the first screw 31 from falling due to loosening. When the first screw 31 is screwed in, the compression spring 32 transmits the pressure to the adjustment seat 2, and the adjustment seat 2 moves downward, shortening the distance from the support of the table frame 1. Similarly, when the first screw 31 is screwed out, the compression spring 32 elongates, the force on the adjustment seat 2 decreases, the adjustment seat 2 moves upward, and the distance between the adjustment seat 2 and the table frame 1 increases. At the same time, due to the fixation of the limiting structure, the adjustment seat 2 and the table frame 1 always remain connected. In this way, the height of the adjustment seat 2 is adjusted so that the adjustment seat 2 has a suitable height to abut against the tool bar 7.
[0045] In another embodiment, there is a clearance area between the adjustment seat 2 and the table frame 1, and the compression spring 32 is located in the clearance area, and the upper and lower ends of the compression spring 32 abut against the adjustment seat 2 and the table frame 1 respectively. Although this embodiment is not shown in the figure, those skilled in the art can easily understand the setting method of this embodiment in combination with the drawings and the description.
[0046] The adjustment seat 2 includes a top plate 21 that abuts against the tool bar 7 and side plates 22 that are located on both sides of the top plate 21 and extend vertically downward. A clearance area is formed between the top plate 21 and the shown table frame 1.
[0047] The compression spring 32 is arranged in the clearance area, its upper end abuts against the adjustment seat 2, and its lower end abuts against the table frame 1. When the first screw 31 is screwed in or out, the compression spring 32 contracts or elongates, and during this process, it still acts on the adjustment seat 2 and the table frame 1, and can still realize the height adjustment and limitation of the adjustment seat 2.
[0048] In addition, as Figures 1 to 3 shown, the limiting structure of the solution of the present application includes a positioning component 4. The positioning component 4 includes a second screw 41, and the second screw 41 cooperates with a nut 42 to fixedly connect the adjustment seat 2 and the table frame 1.
[0049] The positioning component 4 fixes the adjustment seat 2 and the table frame 1. After the adjusting component 3 adjusts the height of the adjustment seat 2, the adjustment seat 2 is fixed to the table frame 1 through the positioning component 4, so as to ensure the overall stability of the adjustment seat 2 at a limited height during the processing.
[0050] Preferably, the adjustment base 2 and the tabletop frame 1 are provided with assembly holes 23 through which the first screw 31 and the second screw 41 pass, and the inner diameter of the assembly hole 23 is smaller than the outer diameter of the compression spring 32.
[0051] Setting the inner diameter of the assembly hole 23 to be smaller than the outer diameter of the compression spring 32 prevents the compression spring 32 from falling into the assembly opening, which is conducive to ensuring the stable limiting function of the compression spring 32.
[0052] Preferably, the limiting structure includes a plurality of connection units distributed along the adjustment base 2, and each connection unit includes an adjustment component 3 and a positioning component 4.
[0053] Setting the connection unit to include an adjustment component 3 and a positioning component 4, after adjusting the height of the adjustment base 2 to make it abut against the tool bar 7, it is fixed by the positioning component 4 to prevent the adjustment component 3 and the positioning component 4 from being disorderly distributed and causing unstable positioning of the adjustment base 2.
[0054] For example, positioning components 4 are respectively arranged on both sides of the adjustment component 3. On the one hand, it strengthens the positioning strength of the adjustment base 2 at the adjustment component 3, and on the other hand, it is conducive to ensuring the accuracy of the height limitation of the adjustment base 2 at the adjustment component 3.
[0055] In one embodiment, as Figure 1 、 Figure 4 、 Figure 5 shown, the adjustment base 2 is provided with a plurality of limiting plates 6 arranged along the length direction of the tool bar 7, and each limiting plate 6 is provided with a plurality of card slots 5.
[0056] Furthermore, the top of the limiting plate 6 is concave to form a card slot 5, and each limiting plate 6 corresponding to a single tool bar 7 is provided with a card slot 5 connected thereto.
[0057] Each limiting plate 6 corresponding to a single tool bar 7 is provided with a card slot 5 for engaging and limiting it, thereby ensuring the overall limiting stability of the tool bar 7. And each limiting plate 6 is provided with a plurality of card slots 5 along its own length, and can be simultaneously engaged with a plurality of tool bars 7.
[0058] As a preferred implementation manner in this embodiment, as Figure 5 shown, there are a plurality of limiting plates 6, and the card slots 5 include a first card slot 51 and a second card slot 52 that are axially offset along the length direction of the tool bar 7. Each limiting plate 6 is provided with a first card slot 51 or a second card slot 52, and at least two limiting plates 6 at both ends are provided with the first card slot 51.
[0059] The limiting plates 6 at both ends are aligned with the first slots 51 to determine the basic position of the blade 7. The middle limiting plate 6 is provided with the second slots 52 axially displaced from the first slots 51 at both ends. When the blade 7 has a tendency to move, due to the dislocation of the first slots 51 and the second slots 52, the left and right side walls of the blade 7 abut against the first slots 51 and the second slots 52 respectively, and the blade 7 cannot continue to move left or right, thus avoiding radial shaking of the blade 7. At the same time, the adjustment seat 2 cooperates with the slots 5 to limit the movement of the blade 7 in the vertical direction. In this way, the working stability of the blade 7 during the laser cutting process is further improved.
[0060] Anything not described in this application can be achieved by adopting or drawing on existing technologies.
[0061] The various embodiments in this specification are described in a progressive manner, and the same or similar parts between the various embodiments can be referenced to each other, and each embodiment focuses on the differences from other embodiments.
[0062] The above is only an embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various changes and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application should be included in the scope of the claims of the present application.
